Neurotransmitter Tryptophan Metabolism Plus
Mental strength begins with cellular metabolism.
This comprehensive test analyzes not only the most important neurotransmitters, but also tryptophan metabolism, mitochondrial activity, enzyme functions, and essential cofactors.
It thus uncovers complex connections – e.g., in long-term COVID, stress-related exhaustion, sleep disorders, or "silent inflammation."
It is aimed at anyone who wants to delve deeply into their mental and physical health, either preventatively or therapeutically.
Ideal for complex questions or chronic stress situations.
Simple urine test for at-home – with in-depth laboratory analysis.
Includes a personal 10-minute discussion of the results with the ORY expert team.
Our most comprehensive tool for holistic neuroregulation.

→ Important points for family and partner diagnostics
Added value for the whole family: Joint diagnostics reveals important connections, supports genuine prevention and helps everyone to better understand nutrition, stress and health – and above all, to more easily take concrete, helpful steps.
- Clear data per person: For each person tested, we need their name and date of birth so that the laboratory can clearly identify them.
- Individual email address: Each person needs a unique email address for secure digital access. If this is not possible, we will send the results as a PDF to a shared address.
- Clear labeling: Samples and forms must each be assigned to the correct person.
💚 Together we make people healthy.
→ Important: Follow the instructions correctly
Please read the instructions carefully. Correct preparation is crucial so that your sample – stool, urine, saliva or blood – can be analyzed cleanly and meaningfully.
Diagnostic time: Please be patient.
Our laboratory analyses are precise, in-depth, and comprehensive. Therefore, the evaluation typically takes 7–21 days after the sample arrives at the laboratory.
Good diagnostics take time – and that's exactly the quality you get from us.

→ For possible reimbursement by your private insurance
Here's how the process works for a possible reimbursement by your private insurance:
- A short online consultation with one of our therapists: During this consultation, we will clarify your symptoms and create a suitable, brief medical history.
- Referral for the appropriate laboratory tests: After the consultation, you will receive a referral which you can submit to your private insurance company.
Many private insurance companies cover the costs in full or in part – some, however, do not cover them at all. Unfortunately, this is normal and depends entirely on your policy. We will guide you through the process as best we can.
